Welcome to Presray Corporation.
Since 1955, Presray has become the leader in protective door systems.  We started with pneumatic lifting devices for the space industry and soon used this sealing expertise to create engineered watertight doors and barriers. Today we make airtight doors and security doors, too.  Presray systems now protect hundreds of business, governmental and civic facilities, plus sensitive laboratory situations.

Our product line includes standard designs, all of which can be modified for custom requirements.
